MACHINE FOR COMBING COTTON AND THE LIKE.

' Application filed March 28, 1922. Serial No. 547,356.

T 0. all whom it vita-y concern:

' Be it known thatL'JiiMns Honnrnon, a subject of the King of Great Britain, residing at 261 Derby Street, Bolton, in the county of Lancaster, England, have invented new and useful Improvements-in Machines for Combing Cotton and the like, of which the following is a specification.

The invention relates to improvements in or relating to machines for combingcotton and the like and has for its object to improve the method of actuating the detaching rollers and to provide simple mechanism therefor.

In combing machines of the Heilman type it is customary to employ a group of three detaching rollers While in those of the Nasmith type four detaching rollers are usually employed.

In the former case, as is well understood, one of the three rollers is a prime mover. and transmits its motion by, frictional contactto the other two rollers whereas in the Nasmith machine the two bottom rollers are geared together while the upper, rollers are driven by their respective bottom rollers by frictional contact.

Hitherto it has been customary to impart to said detaching rollers a partial reverse and subsequent forward movement and for this purpose it has been necessary to employ various somewhat complicated arrangements of mechanism.

Now according to the present invention said partial reverse movement of the detaching rollers and the consequent complicated arrangement of mechanism are dispensed with and the following method and mechanism are employed for performing the detaching operation.

For the purpose of this invention preferably four detaching rollers are employed as in the Nasmith machine and the lower one of the front rollers is continuously rotated in a forward direction and the lower back roller is intermittently rotated in a forward direction which imparts to the cotton under treatment the action and movement hereinafter described.

The front end of the lap is fed forward by the combined action of the feed rollers and nippers as at present to the continuously rotating front detaching rollers which draw off the combed fibres and the piecing of the the back rollersjcommerce to rotate in a forward direction drawing with themthe fibres and after a certain amount of movementhas taken place the back rollers stop while the front rollers continue to rotate and .the back end of the fibres continues to advance which causes the same to buckle and the backend thereof to. fall down between the front rollers and the back rollersleaving a length of cotton for the next delivery to overlap thus making the piecing.

Any suitable gearing may be employed for driving the front rollers continuously and the back rollers intermittently from the cylinder shaft but the following mechanism,

is that which it is preferred ,to employ for that purpose. i 1

In the accompanying drawings Figure l is an end elevation ofgearing suitable for driving the front and back detaching rollers in accordance with the present invention. p

Figure 2 is a diagrammatic side viewthereof and v r 1 1 Figures 3, 4; and 5 are diagrams, illustrating three phases of the detaching and piecing operations carried out in accordance with the present invention. y 1

Referring to Figures 1 and 2, 1 represents a portion of the frame of the machine, 2 represents the cylinder, 3 represents the cylinder shaft, 4 represents a portion of the driving wheel, 5 5 represent the front detaching rollers and 6, 6 represent the back detaching rollers.

The front detaching rollero is continu v ously driven from the cylinder shaft 3 by i the following means. Upon said shaft 3 is fixed a spur wheel 7 which gears with an detaching roller 5 said shaft being extended for that purpose as shown.

with an idler pinion 17 mounted upon a stud 18 carried by the frame 1 and said pinion 17 is of such width and is so arranged that it'gears with and drives an idler spur wheel 19 mounted upon the shaft 10, and upon the shaft 6 of the back roller 6, which is eX- tended for that purpose, is a spur wheel or pinion 20 with which the spur wheel 19 gears and drives.

Once in every revolution of the boss 4 the pin 13 engages the star wheel 15 and imparts thereto and consequently to the spur wheel 16 a partial revolution which intermittent motion is communicated by the spur wheel 16 to the pinion 17 and through the spur wheels 19 and 20 to the back roller 6. y

In the diagram Figures 3, 4 and 5 w represents the nippers of the combing machine,

' the preceding tuft 2 being in the nip of the back detachingrollers 6, 6 which are assumed to be momentarily at rest.

Upon nipping the tuft 3 the continuously rotating rollers 5, l carry it into the position illustrated at Figure 4 where it meets the tuft .2 at the nip of the back detaching rollers 6, 6- which now rotate and effect the piecing and continue to rotate .until the whole of the tuft .2 has passed through the nip of said rollers 6, 6 at which point the rotation of the same ceases while the front rollers 5, 5 continue to rotate.

The effect of this action is that the tuft y buckles between the rollers 5 and 6 as shown in Figure 5 and its rear end follows the periphery of the roller 5 in its movement and finally assumes the position occuparting to said rollers a continuous rotary motion in a forward direction and to the back rollers an intermittent rotary motion the necessity for a partial reverse motion of both the front and back rollers and the consequently complicated mechanism necessitated thereby are obviated.

It will be understood that the details of construction of the mechanism hereinbefore described may be modified without departing from the principle-of the invention.

\Vhat I claim as my invention and desire to secure by Letters Patent is':

In a combing machine, the combination of a driving shaft, two pairs of rollers. disposed in parallelism with said driving shaft, a spur wheel secured to said driving shaft for rotation therewith, a pair of rigidly connected idler spur wheels one in mesh with said first spur wheel, a pinion carried by the shaft of one of the rollers of one of said pairs in mesh with the other of said idler wheels whereby said roller is continuously rotated during rotation of the driving shaft, a boss carried by said driving shaft. for ro tation therewith and having a pin extending beyond its periphery, a countershaft in parallelism with said driving shaft and having Secured thereto a star wheel adapted to be operated by said pin once for every complete rotation of said boss, a spur wheel secured to said countershaft, an idler pinion in mesh with said spur wheel, an idler spur wheel in mesh with said idler pinion, and a pinion secured to the shaft of one of the rollers of the other pair, whereby said roller is intermittently rotated during rotation of the driving shaft.

In testimony whereof I have signed my name to thi specification.
